What’s the Difference Between DV, OV, and EV Certificates?
Although all X.509 certificates
use similar methods to protect and validate your data, a useful way to categorize them is by the validation method used by the certificate authority (CA). Domain Validated (DV) is the lowest level of validation, and verifies that whoever requests the certificate controls the domain that it protects. Organization Validation (OV) and Extended Validation (EV) require further validation, including information about the business or other entity covered by the certificate.
DV Certificates Domain validated
or DV certificates
are the most common type of SSL certificate. They are verified using only the domain name. Typically, the CA exchanges confirmation email with an address listed in the domain’s WHOIS record. Alternatively, the CA provides a verification file which the owner places on the website to be protected. Either method confirms that the domain is controlled by the party requesting the certificate.

SSL.com’s OV/IV Code Signing
certificates are an economical way to protect your code from unauthorized tampering and compromise, and are available for as little as $64.50 per year
OV Certificates Organization validated
or OV certificates
require more validation than DV certificates, but provide more trust. For this type, the CA will verify the actual business that is attempting to get the certificate (the information required for OV certificates
). The organization’s name is also listed in the certificate, giving added trust that both the website and the company are reputable. OVs are usually used by corporations, governments and other entities that want to provide an extra layer of confidence to their visitors. Aside from SSL/TLS certificates, OV is also commonly used for code signing
, document signing
, client authentication
, and S/MIME
SSL.com offers the following OV certificates:
EV Certificates Extended validation
certificates provide the maximum amount of trust to visitors, and also require the most effort by the CA to validate. Per guidelines set by the CA/Browser Forum, extra documentation must be provided to issue an EV certificate (as described in EV SSL Requirements
). As with OV, EV lists the company name in the certificate itself. An EV code signing certificate
is required to sign Windows 10 drivers and provides an instant SmartScreen reputation boost. If you’re not sure which code signing certificate you need, please read this FAQ
